I own two pairs of Xeros, but full shoes, not sandals like these. One low rise, the other semi-boot height for the winter. Adequately wide for the toes, zero

rise. which is the most important thing. I personally remove the insoles, so I'm basically walking on a 5mm sole just like the sandals. I walk on asphalt in the city, and a lot on sand, gravel and pebbles. They're indestructible.
